Ring of Blades (Arcana)
Level: Priest 3
Mana: 30. Persistant. Base Success: 100%.
  Casting this spell, you conjure a ring of spinning blades around your body; these blades move with you, striking any creature within 5 feet of you once each turn to inflict [1d6 + caster level] points of slashing damage. They take you no time to direct or utilize, and you can take actions normally while they fly around you, but beware -- they strike allies as readily as enemies.
   Huge size and larger creatures cannot make effective use of this spell.
